[j-nsp] IPv6 link-local addresses

Hi,
Is there a way to manually set the link local address of an interface in
8.x?  I am running into a problem where I have T1 interfaces connected
through a CT3 and they both have the same link local address.  This is a
back-to-back CT3 using logical-routers:

admin at m20-re0# run show interfaces t1-0/1/0:0 | match fe80     
        Destination: fe80::/64, Local: fe80::2a0:a5ff:fe28:f

[edit]
admin at m20-re0# run show interfaces t1-0/1/1:0 | match fe80    
        Destination: fe80::/64, Local: fe80::2a0:a5ff:fe28:f

The intended result is to have different addresses so my OSPF3
adjacencies can come up:

Sep 18 21:34:49.963624 OSPF packet ignored: Our interface address is
source address fe80::2a0:a5ff:fe28:f

I've attempted to use the 'preferred' keyword on the v6 address, but
that didn't work.

Any insight would be appreciated.

Thanks,
eric
